IMPROVEMENT lN BOX-IRONS.

Specification forming part of Letters Patent No. 198,314, dated December 18, 1877; application filed August 4, 1877; patented in France October 8, 1874.

To all whom it ma/y concern:

Be it known that I, JEAN GEORGES RUGER, of Paris, France, mechanist, have invented an Improvement in Box Sad-Irons; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed sheets of drawing, making a part of the same.

This invention relates to that class of sadirons called box-irons, which are heated by combustibles within them.

The improvements have for their obj ect to so regulate the combustion as to enable the heat of the iron to be varied at will.

The improvements consist, first, in providin g one end of the iron with a partition-plate, so arranged as to form an air-inlet passage or chamber; and, second, in a movable chimney for the escape of the gaseous products of combustion, the chimney being adjustable to discharge the gases in the direction least liable to interfere with the operator or to injure the material. The chimney has the further advantage of being out of the way of the iron handle, which is not liable to become heated by its proximity.

The iron is a metal box, heated internally by fuel burning upon a grate, the combustion being governed by regulating the air-supply.

Figure 1 of the accompanying drawing shows a side elevation of a box-iron, the chimney being turned toward this side. Fig. 2 is aplan, with the top of the iron removed. Fig. 3 is a rear end elevation; Fig. 4, a section taken through the longitudinal axis of the iron, the chimney being turned backward. Fig. 5 is a plan of the entire iron; Fig.6, a plan and face view of the door of the ash-pan.

The same letters of reference indicate the same parts in all the figures.

. The iron shown is of the kind used by hatmakers; but it will be understood that the form may be varied ad Zt'bitum.

A, box-iron, with apolished face, a B, grate for the fuel, supported on small blocks b, cast or fixed to A; O, partition, by which the air is conducted beneath the grate B, the partition separating what I will call an inlet-air chamber from the fuel-chamber, with which it can only communicate between the grate'bars B, so that the incoming air for combustion is separated from the outgoing products of combustion. The air-supply is regulated by the rotary plate or valve E, covering the air-inlet openings d d formed in the heel-plate D of the boxiron, the one above and the other below the level of the fire-grate. The plate E turns on a center, 6, and is adjusted to cover more or less the inlet-orifices d d G, cover hinged at g to the heel end of the iron, and locked at the front end by a thumb-screw, g. The chimney H is mounted over an aperture in cover G at the back part, in which it is secured by the flanged thimble h J, ash-pan K,handle made of nonconducting material, mounted to turn between uprights k k fixed on or formed with cover G; L, Fig. 6, cover-plate, with spring-catches l l for the opening 11, at which the ash-pan is emptied; M, sheet-iron baffle-plate,fixed by screws mto cover G,the burnt gases escapingthrough m" m to the chimney H. The gases are thus obliged to traverse the whole length of the iron, so as to impart the maximum amount of heat, the air-supply being also distributed equally through the whole area of the gratesurface, thus rendering the combustion uniform at all points.

I claim- 1. The combination, with thebox-iron, having the heel-plate D, provided with air-openings and regulatingvalve, as described, of the partition 0, arranged substantially as shown and described, for the purpose specified.

2. The combination, with a box-iron, as described, of the horizontally-adjustable chimney, substantially as andfor the purpose speci fled.
